The purpose of this extension is to pre- 95 twoor more ot which are filled with hot palmvent the foaming and boilingoil in the first oil, and in which the lower rollers of two or trough Bfrom rislng and foaming over into more of said pairs revolve, so thatthe same the next trough B2. The water dripping from are continuallycoated with oil, a feed-table the wet plates and the steam generated byfrom which the sheets are fed between the the iirst. pair of rolls andcarried down by the roo 5o first pair of rollers and by the heat ofwhich rolls into the hot oil will cause the oil in the the moisture ischiefly evaporated from the first trough to foam and boil, and thisextensys sion serves to prevent boiling over into the trough B2. The oilin the last trough B2 will remain entirely placid, as all moisture isfreed from the sheet before it reaches the last pair of rolls, so thatno moisture or steam can be communicated to the oil in the last troughB3. The oil in this last trough can therefore be and is heated to therequisite high temperature torproduce the most complete and perfectfluxing of the sheet, and also to raise the temperature of the sheetitself to the required pointto produce the best results when it issubsequently immersed in the tin pot. The last pair of rolls and thelast oil-trough B3 may thus be and in practice are heated to a muchhigher temperature than the first pair of rolls and the irst trough B',the middle pair of rolls and trough being heated to an intermediatedegree. Each of the compartments B B2 B3 is furnished with an outlet b5,closed by a plug 196, so that the oil may be drawn out when desired.

D D D D D D are three pairs of hollow steam-heated smooth metallic rollsjournaled in suitable bearings F F', which are mounted on the frame ofthe machine in suitable vertical guides F2, so that the upper bearing Fof each pair of rolls may be free to move up and down in said guides.

VThe three pairs of rolls D D D D D D are mounted directly over thethree oil troughs or compartments B B2 B2, and the lower roll D isimmersed for a fraction of its circumference, preferably aboutone-fourth thereof, in the oil or flux in said troughs. The bearing orjournal F of the upper roll of each pairis separated from the lowerjournal F, upon which it rests, by an adj usting-screwf, so that therolls may be set parallel to each other and the space between themadjusted so as to admit of the passage of the sheet between the rollsand at the same time permit the rolls to come close enough togetherafter the sheet has passed to practically transfer the flux or oil fromthe lower roll to the upper one, and thus supply the oil to both sidesof the sheet and thoroughly coat both sides thereof therewith. To permitof this slight up-and-down movement of the upper roll of each pair andatthe same time keep the requisite pressure between the rolls, we providethe cap-plate F2 of the journal-guide with adjusting-screwsf, which actagainst a spring f2, that bears upon the journal-box F. By this meansthe rolls may be allowed to come together or nearly together when thereis no sheet passing between them, and thus cause the lower roll totransfer the oil to the upper one and then yield'sufflciently to allowthe sheet to pass between them. 2

The rolls D D are all hollow and heated by steam admitted to each pairfrom the steampipe C through separate branch pipes c4 c5 c6, eachfurnished with separate regulatingvalves c7, so that the temperature ofeach pair of rolls may be governed as required. A

E is the feed-table, about on a level with the meeting surfaces of therolls D D', from whichthe sheets are fed into the first pair of rolls.

E is the discharge-table, preferably arranged at an incline andfurnished with a sheet-delivery roll E2 at its inner edge.

G is the oil feed or supply tank from which, 2

through a feed pipe or nozzle g, furnished with a regulating-valve g',the oil is fed or supplied to the troughs B2 B3 in a regular manner, soas to keep the same full and the rollers D D immersed therein to aregular and uniform depth. This oil-feed tank has a steam-jacket g2 forheating the same by steam admitted through the branch pipe c2, the samebeing furnished with a valve c2 to regulate the temperature.

lfl is the drip pan or tank supported on the frame A below the oil-potB, the same being large or wide enough to catch drippings from everypart of the machine. It is furnished with a well H', from which leads apipe h to a pump K, which forces the oil up into the supplytank Gthrough the connecting-pipe 7c. The pump K is operated by pitman-rod K,connected to a crank-pin n on the gear N on the driving-shaft N. Y

The rolls D D are driven from the drivingshaft through a set ofconnecting-gearing N2 N3 N4, the gears N2 being on the lower rolls, thegears N3 on the upper rolls, and the gears N4 on intermediate shafts N5.

The discharge-compartment B4 of the oil` pot B is furnished with anoutlet b2, provided with a valve or nozzle 198, through which the oilmay flow into the drip-pan below.

rlhe feed-tank G is from time to time supplied with oil to replace thatadhering to the sheets passing through the machine, or, if preferred,the fresh oil may be put in the drip-pan H. By means of this tank andits feed-valve we automatically keep the troughs B B2 B3 supplied withoil.

In operation the wet sheets as they come from the water bath are fedbetween the several pairs of rollers D D', whereby the same aresimultaneously dried, heated, and fluXed, the sheets passing out ontothe delivery-table E with every particle of moisture driven therefrom,heated and fluxedV and ready to be placed in the tinning or metalcoating bath. By means of the steam-regulating valves and the separatebranch pipes leading to the several pairs of rollers the first pair ofrolls and the oil in the first trough B 'may be kept at acomparatively-low temperature, so that the moisture and steam producedfrom the wet sheets will not cause too violent foaming and boiling ofthe oil. of rolls and the oil-trough B2 are heated to a higher degree,andthe nal pair of rollers and trough are heated to a still highertemperature, so that the iiuxed sheet will be delivered from the machinein proper condition to en-V ter the tinning-bath. The rolls revolvecontinuously, and at the intervals when no sheet is between the rollsthe flux or oil will be IOO IIO

The next succeeding pair transferred to the lower roll of each pair tothe upper one, so that the oil or flux will be properly supplied to bothsides of the sheet. During this operation the overhead feed-tankcontinuously supplies or feeds the oil to the oiltroughs, thusmaintaining the oil at a proper level, and at the same time the pumpredelivers the oil collected in the well of the drippan into thefeed-tank.

By means of this machine the wet pickled sheets may be very quicklydried, heated, and liuXed without giving any opportunity for the same tobecome oxidized or tarnished on either side and without waste of the oilor iiuX and without danger of the same getting on fire, the work beingalso done automatically and without the necessity of hand labor.

The number of pairs of rolls which we pref,- erably employ is three,as-shown in the drawings; but the number of pairs of rolls may beincreased or diminished, if desired.

As the oil in the first trough will be in a boiling, foaming, orfrothing condition, owing to the steam and moisture from the wet sheets,it will foam up and come in contact with the rst roll D, even thoughthis trough be not full of oil.

As shown in the drawings, the oil-supply tank G delivers the fresh oilonly to the last two troughs B2 B3, the single nozzle employeddeliveringthe oil midway between them on the partition b. It generally is notnecessary to deliver the oil from the supply-tank directly into theIirst trough B', as some foaming up of the oil in the second trough B2willv take place from time to time in the space Z210 between the-secondroll D and the extension h2 of the partition b, and boil or foam oversaid extension into the trough B', and thus supply said trough with oil.The oil does not foam up over the partition b, as the moisture and steamare mostly driven oft from the sheets by the first pair of rolls andpractically all driven off as the sheet passes the second andstill-hotter pair of' rolls, so that the steam and moisture arepractically confined to the space between the rst two pairs of rolls andthe space on the front side of said rst pair of rolls.

By employing a series of pairs of graduated heating-rolls-that is tosay, rolls each successive pair of which are heated to a highertemperature than the preceding pair-as the means or instrumentality fordrying, heating, and luxing the wet pickled sheets said operations areperformed simultaneously or practically simultaneously, so that thesheets have not time or opportunity to become tarnished or oxidized,their surfaces being protected or coated at all times either by thewater or by the oil as they pass through the machine, and we therebysecure at the same time the important result of at once preventing unduefoaming, boiling, and waste of the oil and the proper heating andthorough Huxing of the sheet, as the wet sheet is first op` erated uponand its water chiefly driven of by the rst pair of rolls at atemperature so low as not to produce violent or undue foaming andboiling of the oil and as the sheet, after being further dried andheated by the next pair of rolls and'their hot oil, is then finallyheated to the proper degree and thor' oughly fluXed by the last pair ofrolls, the temperature of which may be raised to any desired degreewithout causing any agitation of the oil in theiroil-trough, and theWorkis also done automatically. As the lower heated rolls of each pairrevolve directly inthe several oil troughs or compartments, the rollsthemselves serve as a means for heating the oil in the oiltroughs and ofkeeping the oil in the different troughs at the graduated or differenttemperatures of the rolls themselves, as desired.

The feed-table E should be slightly inclined to permit the Water tocontinually drain from the wet sheet as it is fed to the first pair. andenters between them, and it should also be made of slats or providedwith corrugations in or openings through it to prevent the wat-erfromadhering to its surface unnecessarily. The object of employing an openor corrugated feed-table and the object of inclining the same are toprevent the sheet from carrying an unnecessary amount of water ormoisture to the iirst pair of rolls.

By combining with the oil-troughs with drying, heating, and fiuxingrolls which are hollow and heated by steam admitted to their interior weare enabled not only to heat the rolls to different degrees oftemperature, as desired, but also to prevent the oil from catching fireand the waste and danger incident thereto.

We prefer to locate the oil-feed nozzle g between the pairs of rolls andnot to deliver the oil directly upon the rolls from this feed-nozzle, asthe oil will be more evenly distributed over the surface of the upperrolls by transferring it from the lower ones; but this arrangement mayof course be varied, if desired.
